Ok, so I checked the forums for my problem and found similar issues, but I'm hoping my exact problems can narrow down the issue to my truck.
- I have a 2011 f-150 w/ retrofitted non factory HIDs bought from another member. Lights have worked great for a year...in the last week I have noticed that when my truck is in gear I could not turn my headlights on..never had that problem before. So I threw it in park and they cane right on. Ok so next it evolved to my driver side headlight would not come on with my other. I turned off the lights, turn off the truck, restarted and both turned on. 1 day later no lights whatsoever. Parking lights, signals, flashers all work.
- ground is good, fuses appear to be good, all connectors plugged in tight and I even checked both ballasts w an extra I had... Any tips..thinking relay or harness but I'm not an electrical guru. Thanks!!

 

Sorry I should note before they crapped out completely I got them to kick on by turning the **** on/off quickly but it was for a sec and I can't repeat it.

 

Any takers?

 

check your fuses. you may have busted one by turning them on and off quickly. also try disconnecting the battery for a few minutes.

 

Did both, both appear good I'm going to have another go at it in a bit.

 

or the relay fuse.

 

I'm hoping that's it I went through the whole thing tiday and it's all I can possibly think of.. It's one of the mega ones not a little one so it'll have to wait for a trip to the store tomm...thanks for the input though.

 

Notice the pin that rusted off from the relay harness

 

Was the relay on the harness...lot easier to go through during the day than at night when you're stranded...thanks all!
